Frequently Asked Questions

Is topic "xyz" examinable? All topics included in the lectures are examinable with the exception of the polynomial representation of cyclic codes.

Do I need to remember long formulas? In general you are not expected to memorize long complicated formulas. However you will be expected to remember some basic and important formulas such as the Shannon formula.

How many problems will I choose in the exam? There are no choices any more in the final exam. This is to discourage game playing and selective revision.
